These two drafts are both for 15 shafts and they both employ a 3-end (jeans) twill as their structure. The first draft is based on a block profile for 5 blocks. The second draft follows the same basic shapes, but the lines are smoothed out in this networked version. The network is based on a 3-end initial. The networked version is curvier, but the edges are less clear-cut; the fuzziness is characteristic of network drafting.
These drafts are both from my files and were probably done before 1994. They were candidates for Network Drafting: an Introduction (see sidebar), but never made the cut. They'd be great for monochromatic apparel fabric in fine cotton or silk.
